PUMP.

Specicaton of Letters Patent No. 23,443, dated April 5, 1859.

To all whom it may concern:

Be it known that I, VILLIAM R. BROWN, of Cleveland, in the county oit' Cuyahoga and State of Ohio, have invented new and useful improvements in Hydraulic Pumps, and do hereby declare that the following is a full and complete description of the construction and operation of the same, reference being had to the accompanying drawings, making part of this speciication.

Figure l, is a side elevation of the pump. Fig. 2, is an end view. Fig. 3, is a vertical cross section. Fig. 4, is a horizontal longitudinal section with the barrel and one head removed, and Fig. 5, is a horizontal section of the barrel showing the Wings or diaphragm and lower valves. Figs. 6, 7 and 8, are different views of one of the valves.

The barrel of the pump A, may be made of cast iron, or other suitable material. The diameter and length will depend upon the uses to which the pump is applied. For ordinary use in common wells or cisterns, the barrel may be about eight inches in length, and eight inches in diameter. The inside should be bored straight and smooth, and the ends made exactly parallel with each other. A ridged diaphragm is stretched across the interior of this cylinder at an obtuse angle, as seen at B B, and is secured to the barrel at its respective edges by screwstwo of which are seen at O, C, Fig. l. The middle portion of this diaphragm is exactly in the center of the barrel A, the two parts at their' junction forming a pipe D, through which a round rod passes, and upon which the barrel articulates. The lower valves E, E, rest upon this diaphragm, and are seen in Figs. 3 and 5. The two ends of the barrel A, the ends of the diaphragm B, and the upper side of the pipe D, are packed, as indicated by the shaded lines F, in Figs. 3 and 5. This packing may be either met-allie, or composed of leather. The barrel A, thus fitted up and arranged, is mounted between two circular heads G, H, Figs. l, 2 and 4. ln Fig. 4, the head H is removed. These heads are furnished with legs I, as seen in the several gures, by means of which they are fastened to a platform.

In Figs. 3 and 4, K represents a stationary diaphragm, which is attached to the two heads by screws as seen at L, L, in Fig. 2. The position of the diaphragm is indicated at K in Fig. 2. This diaphragm has two valves J and J opening upward, as Seen in Fig. 3. The edges M M of this stationary diaphragm are packed in the same manner as are the ends of the barrel and the ends of the diaphragm B.n It fits closely the inner surface of the` barrel A, its middle portion being grooved longitudinally, to iit the upper side of the pipe D. The heads G, H, are held irmly against the `ends of the bar rel by the long screw bolts N, N, N, N, N, N, six in number, and the center bolt D', which passes throughthe pipe D. The space contained within the barrel is thus divided into four compartments, seen at O, P, P and Q, Fig. 3, P and P occupying the middle portion of the barrel.

In Fig. l, R represents a suction pipe that extends from the lower chamber O to the fountain of water. S, represents an exit pipe, leading from the chamber Q. T, represents another exit pipe, leading from the same chamber, and is designed to convey water to a greater elevation. U, repM resents a valve seat or chamber, in which is placed a conical section valve, and may consist of two, three, or more parts, and may therefore form a bi-cuspid, or tri-cus pid valve, shown in Figs. 5, 6 and 7 Its position is also shown by the dotted lines in the valve seat in Fig. 2. This valve is formed by dividing a hollow cone into two or more equal parts as seen at U in Figs. 6 and 7, indicated also by the dotted lines in Fig. 6. The apex of the cone must be placed upward; its base must rest upon a horizontal valve seat, whose circumference is equal to the circumference of the base of the cone. The sides of the valve seat rise vertically from the outside of the valve seat (which has a horizontal thickness equal to the thickness of the walls of the hollow cone) to a height equal to the length of the cone. By means of this arrangement, the outside of the sections of the cone, can never assume a position that will throw their specific gravity outward, but, on the contrary, th-e several sections of the cone will always incline inward, and when not 4forced apart by the passage of the current of water will lie in contact. A pressure of water upward opens the valve, and allows a free and uninterrupted flow of water, and as soon as the water ceases to How, the valve closes, and prevents the return of the water.

This pump is operated by means of a handle V, which is secured to the side of the barrel A, or the barrel or cylinder may flows into the chamber P, and by reversing the action the valve J is opened, while the valve J is closed, thus by every stroke of the arm V the chamber@ is supplied with y Vwater, which finds any, exit by the pipe .S

or the bi-cuspid valve UV. In this movement, the barrel A, with the diaphragm B, is caused to rotate backward and forward a distance of about twenty degrees, the diaphragm K remaining stationary. By the action of the valves E and E and J and J 4the water is forced into the chamber Q, and

from thence through the pipes S and T, as described, the Valve U opening outward as indicated by the dotted lines in Fig. 6, a vertical section and base of the same being shown in Fig.v 7 at U.

I am aware that pumps with an oscillating diaphragm are not new, but

What I claim and desir-e to secure by Letters Patent of the United States is:

l. I claim the bicuspid valve constructed substantially as herein described. 2. I claim the arrangement of the bicuspid valve in connection with theoscillating pump, the whole being4 constructed, ar-

ranged and operated substantially as set forth, for the purposes described.
